I hate this card and the entire demon hunter class.
First of all this card should be LEGENDARY! Not that is so strong you can't have 2 in your deck, but the effect is so unique and complex it should.
DH defenders say most calsses have a way to deal with (sucks to be a druid), and it is true but if you dont have the answer in your hand the game is as good as over. They also say its a 9 mana 10/10 do nothing, -1 attack on all enemy minions and 1 unhealable damage may not be much but it's definetly not do nothing.
I doubt you will put this in a deck where you just simply play it from hand as a 9 mana 10/10. DH can reduce it's cost to 6 or 7 with Skull of Gul'dan or Raging Felscreamer, pull it from your handwith Fel Summoner or your deck with Pit Commander.
A while ago blizz made a big deal of giving each class their identity with strengths and weaknesses, including cards revealed in this expansion DH has:
-good draw
-2 silence cards
-board clears
-small single target removal
-healing
-weapons and weapon buffs
-direct damage
-good tempo cards
-big minions
-minons with board clears attached
-mana manipulation
-combo disruption
-rush minions
-token generation and some token synergy
-combo and OTK potential
-can ignore taunts
So right now for me it looks like blizzard has no idea what this class is and are throwing everything at the class waiting to see what sticks
